Saw the first two episodes of the first series the other day. It's a strange combination of rubbish and brilliant.
The writing's pretty terrible, on the micro scale... virtually every scene is one character pulling rank on another, be it cop to cop, gangsta to gansta, cop to gangsta or whatever. "Goddammit, MacNulty, you've fecked up"... it's like a Fry and Laurie parody. In the first episode, MacNulty tells a judge something he shouldn’t – we see this, and are then told it about 8 more times, “MacNulty told some goddamned judge...”, “MacNulty, what the goddamn feck are you doing? The Chief just told me you shot your mouth off to some goddamned judge...” That’s just rubbish. And as for the gangstas, they’re so obviously written by a white guy it’s not true. Every expression they use has been lifted off a Snoop record. Nigga please.
On the other hand, the story’s totally compelling, so I’m clearly going to end up watching the whole lot.
